' To all whom t may concern:

Fe it known that ll, Herner J. Geist/ian, a citizen of the llnitedStates, and a resident of Flew York city., borough of Manhattan, FlewForli, have invented certain new and useful improvements in 1WovenFlastic Fabrics, of which the following is a. specihcation.

. 'lfhe object of my invention is topi-Ovide a i fabric adapted to clingor adhere to acontigir ous surface to retard slipping thereover; and` tothis end the invention comprises-the novel details of improvement thatwillbeinore fully hereinafter set forth and then pointed out in theclaims.

Reference is to behad to the accompanying drawings., forming partliereof,.wl1ere1n- Y Figure l. is a face viewfof a piece ,of fabricembodying my invention. Fig; Q is an ciragln the drawings the numeral lindicates generally my improved fabric, comprising strands of threadsinterwoven with elastic strips or warps 2 in such manner that portionsof the latter will be on one side of a line passing centrally across thefabric, and pi'eferably such portions of the elasticwarps will be ex*posed on the surface of the fabric. rlhe elastic strips or warps 2 areshown extending par allel with the fibrous or ,cotton Vwarps 3, and inproducing the exposed portions of the elastic or rubber strips in thefabric l have illustrated'a certain number or series of the weftthreadsat t, crossing over portions of certain rubber strips and beneath otherrubber stri ps,

a' and another series of weft-threads at t, cross- M ing under certainof the Fret-mentioned rubbeistrips and over certain of thesecond-inentioned rubber strips, and so ony` alternately f throughout'the various series of weft-threads, thereby producing interspersedrubber warp portions E2, eirposed on one surface of the fabric, andlsuch eaposed warp portions are at one side of the fabric, and thushave-ia tendency 4over the cotton warps, as shown.

to curl the fabric like a spring. lhc projecting portions 2 of therubber strips or bands 2 being interspersed upon the surface of thefabricpresent a gripping or friction medium superior to that produced byfibrous threads alone where rubber strips are wholly embedded beneaththe surface of the threads or strands in well-l nown elastic fabrics.

-ln Fig. 5 is illustrated a manner of weav ing the fabric to produce theresults described,

la short and narrow portion of the fabric being u2 and il, under rubberQ", and over 2f, and

thence in the return said weft passes around and under the outer rubberwarp 2f and under.

28, d., 2, and 2", passingfrom a under and lnthis illustrative form ofmy inover the cotton warps 3, asshown. The weft is similarly woven for acertain number of picks--say ten, (1n serles of live palrs ofpiclrs)-erposingfor a certaln length at Q part of the rubber warp 2e, sothat such part is uncontined. rlhe neat similar series of picks-sayten-alternate in their passage with respect to warps Qcand 2ethat is tosay., the weft passes under rubber warp 2 and over and under f2,exposing at 2 part of warp QIbut out of line transversely with theexposed part of 93., the weft passing under and ln Fig. 2 thirteenrubber warps are shown, while in Fig. 5 but tive such warps are shownfor purposes of illustration. rlllie weft-threads pass around the rubberwarps at the edges of the fabric, and each second rubber warp hascertain portions exposed, and the intermediate rubber warps are allinterwoven with the weft. ln the example illustrated a certain series ofweft-threads pass over three rubber warps andV under the fourth rubberwarp, and the neat series of weft-threads pass over three other rubberwai-ps andnnder the corresponding fourth rubber,and so on alternately,whereby each second rubber warp has portions er posed, but out oftransverse line with the adjacent eaposed rubber` resulting in producingtransverse lines of exposed rubber, the adjacent lines alternating inposition in the longitudinal direction ofthe fabric. Exposed rubberwarps arethus interspersed over the surface of the fabric.

it will be obvious that the particular manner of weaving shown and therelative l0cations of the exposed rubber warps may be altered, as moreor lessof the rubber warps l0 may be exposed and the alternatingarrangement of the exposed portions 2a may be changed. in Figs. l and2'ibrous warps have been omitted for the purpose of illustration, itbeing understood that the number of fibrous l'5 warps may be 'varied tosuit requirements. The elastic warps atthe selvage are not shown asexposed, the weft binding them in.y it will be observed that certainportions of the weft pass under all the rubber warps, whereby the 2Orubber warps are concealed when the warp is beaten upon the sideopposite the exposed portions Qa, as in Eigs and 3. ,t With the elasticfabric above described'it will be apparent that as the exposed rubberportions or projections come in Contact with a surface against whichtheyare presented the rubber will have a tendency to cause thev elasticfabric to cling or adhere thereto more or less by frictionalcontact.Furthermore,

as the rubber strips or bands are offsetmore or less from the transversecentral line of the fabric they have a tendency to cause the fabric tobend or curl in ther nature of a spring,'or,

in other words, the fabric tends to bendl in the 3S direction towardwhich the exposed rubber projects. j

A My improved elastic4 fabric will be found useful in various relations,such, for instance,

as in hose-supporters, garters, Suspenders,

40 and the like. In Fig. 3 l have shown the fabric applied in ahose-supporter, and thereby when the fabric is fastened around a legthev exposed rubber at 2 and the spring-like action will tend to preventthe supporter from slipping down the leg. In Fig. 4 the elastic fabricis shown applied in the form of a garter and with the like effect ofkeeping it from slipping on the leg, and if used as an armletf it willsimilarly tend to keep in place upon the arm; When the' fabric is usedin Suspenders, the exposed rubber warps and the vspring-like actionwilltend to maintain thesuspenders in proper position upon the shoulders ofthe wearer.

The manner of placing the rubber strips in the fabric, so as toproducethe projecting or exposed portins, and the relative positions andnumber of the latter, aswell as the crossr section or shape of the warpsand other de- 00 tails, may be altered Without departing from the spiritof my invention.

Having now ,described my invention, what claim is-v- As a new article ofmanufacture, a woven fabric having lines of exposed rubber surfaces"reacts interspersed onO the face of the fabric, the exposed rubbersurfaces of one line alternating with the exposedrubber surfaces ofanther line, substantially as described.

2. As a new article of manufacture, a woven elastic fabric having linesof interspersed rubber surfaces projecting beyond the surface of'fibrous threadsof the fabric, lthe exposed rubber surfaces of one linealternating with the exposed-rubber surfaces of another line,substantially as described.

3. As a new article of manufacture, a woven elastic fabric havingelastic warps extending longitudinally of the fabric and intermeshingwith the fibrous weft of the fabric that extends substantiallyperpendicularly to the elastic warps, said weft passing under and overcertain of said warps producing'exposed and concealed portions of saidelastic warps, substantially as described.

a. As a new articlecf manufacture, a woven elastic fabric havingparallel rubber warps intermeshing with certain weft-threads, series ofweft-threads also passing under and over certain rubber warps to produceexposed and concealed portions thereof, substantially as described. l

5. As anew article of manufacture, a woven elastic fabric havingparallel rubber warps intermeshing with the weft-threads of the fabric,one series of weft-threads passing under and over certain rubber warpsand an adjacent series of lweft-threads passing over and under thecorresponding rubber warps providing exposed and concealed portions ofsaid warps, interspersed exposed portions of said rubber warps beingthus presen ted outwardly on the face ofthe fabric, substantiaily asdescribed.' 6.`A Asa new article of manufacture, a woven elastic fabrichaving rubber warps, portions of said rubber warps being alternatelyexposed and concealed on one face in the direc- .tio'n of theirc lengthby the weft, said rubber warps being concealed by theweft ou theoppositeface, substantially as described.

7. A' woven elastic fabric comprising longitudinally-disposed elasticand fibrous warps and fibrous weft, the weft passing under and over thefibrous warps and under portions of the elasticwarps ex posingsuchportions of the latter on one face of the fabric, substantially asdescribed.

8. A woven elastic fabric comprising longitudinally-disposed elasticandfibrous warps and fibrous weft, the weft passing under and over thefibrous warp and under portions of the elastic warps in the same lineand under and over intermediate elastic warps, exposing portions of thel'elastic warps, substantially as described.
